Creating animated GIF from vector data

Inspired by Johannes Uhl's shapefile2gif, I created a vector_to_gif() function in leafmap that makes it much easier to create animated GIF from vector data with only one line of code. The sample dataset used in this notebook is a subset of the dataset retrieved from the shapefile2gif repo. Credits to Johannes Uhl. For more information about the datasets, check out the references below:

33 counties in the United States (1900–2015)", Data in Brief, 43, 108369. DOI: 10.1016/j.dib.2022.108369
